[Bug 306073] [NEW] Long delay during boot using encrypted root filesystem

[robotpoet]

Public bug reported:

Binary package hint: initramfs-tools

After upgrading from 8.04 to 8.10 there appeared a very long delay
(several minutes) during boot, before the appearance of the prompt to
enter the password for the root file system. I decided to investigate
and saw in /usr/share/initramfs-tools/scripts/local-top/cryptroot that
there were some lines to create a very long delay if the ROOTDELAY
variable was not set. Without fully understanding what was going on, I
decided to try adding "rootdelay=5" to my boot parameters, which
actually solved the problem of the long delay during boot.

I suspect many users would not be able to find this solution, so the
default behavior should perhaps be improved.

I have an IDE harddrive with encrypted root on sda5 which is the first
logical drive on the extended partition. This is on a fully updated
Ubuntu 8.10.

~ $ cat /etc/crypttab
# <target device> <source device> <key file> <options>
root 	/dev/sda5 	none	cipher=aes-cbc-essiv:sha256,size=256,hash=ripemd160
swap   /dev/sda2       /dev/urandom     swap
~ $

Please let me know if you need additional information.
